Function Documentation

gboolean crm_cluster_connect ( crm_cluster_t * cluster )

Connect to the cluster layer.

Parameters

[in] Initialized cluster object to connect

Returns: TRUE on success, otherwise FALSE

Definition at line 75 of file cluster.c.

void crm_cluster_disconnect ( crm_cluster_t * cluster )

Disconnect from the cluster layer.

Parameters

[in] cluster Cluster object to disconnect

Definition at line 102 of file cluster.c.

const char* crm_peer_uname ( const char * uuid )

Get the node name corresponding to a node UUID.

Parameters

[in] uuid UUID of desired node

Returns: name of desired node

Note: This relies on the remote peer cache being populated with all remote nodes in the cluster, so callers should maintain that cache.

Definition at line 221 of file cluster.c.

const char* crm_peer_uuid ( crm_node_t * peer )

Get (and set if needed) a node's UUID.

Parameters

[in] peer Node to check

Returns: Node UUID of peer, or NULL if unknown

Definition at line 38 of file cluster.c.

CRM_TRACE_INIT_DATA ( cluster )

enum cluster_type_e get_cluster_type ( void )

Get (and validate) the local cluster type.

Returns: Local cluster type

Note: This will fatally exit if the local cluster type is invalid.

Definition at line 311 of file cluster.c.

const char* get_local_node_name ( void )

Get the local node's name.

Returns: Local node's name

Note: This will fatally exit if local node name cannot be known.

Definition at line 155 of file cluster.c.

char* get_node_name ( uint32_t nodeid )

Get the node name corresponding to a cluster node ID.

Parameters

[in] nodeid Node ID to check (or 0 for local node)

Returns: Node name corresponding to nodeid

Note: This will fatally exit if nodeid is 0 and local node name cannot be known.

Definition at line 175 of file cluster.c.

gboolean is_corosync_cluster ( void )

Check whether the local cluster is a Corosync cluster.

Returns: TRUE if the local cluster is a Corosync cluster, otherwise FALSE

Definition at line 375 of file cluster.c.

const char* name_for_cluster_type ( enum cluster_type_e type )

Get a log-friendly string equivalent of a cluster type.

Parameters

[in] type Cluster type

Returns: Log-friendly string corresponding to type

Definition at line 290 of file cluster.c.

gboolean send_cluster_message	(	crm_node_t *	node,
		enum crm_ais_msg_types	service,
		xmlNode *	data,
		gboolean	ordered
	)

Send an XML message via the cluster messaging layer.

Parameters

[in]	node	Cluster node to send message to
[in]	service	Message type to use in message host info
[in]	data	XML message to send
[in]	ordered	Ignored for currently supported messaging layers

Returns: TRUE on success, otherwise FALSE

Definition at line 133 of file cluster.c.

void set_uuid	(	xmlNode *	xml,
		const char *	attr,
		crm_node_t *	node
	)

Add a node's UUID as an XML attribute.

Parameters

[in,out]	xml	XML element to add UUID to
[in]	attr	XML attribute name to set
[in]	node	Node whose UUID should be used as attribute value

Definition at line 277 of file cluster.c.
